REEL OE-JBEAM.

Application filed September 9, 1919.

To all whom it may concern Be it known that I, FRANK Mossnnno, a citizen of the United States, and resident of Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Reels or Beams, of which the following is a specification.

This invention relates to reels or beams formed more particularly of .pressed steel and like material and on which is wound wire, yarn or the like wherein the heads are called upon to withstand excessive spreading strains; and the object of this invention is to provide a reel or beam of this character with specially constructed means for stiffening and supporting the head plates against such spreading strains.

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the ap ended claims.

11 the accompanying drawings:

Figure 1 is an end view of one form of my improved reel.

Fig. 2- is a sectional side elevation on line 2-2 of Fig. 1.

Figs. 3 and 4; show a modified construction of the beam shown in Figs. 1 and 2.

Fig. 5 is an end View showing a detail of an auxiliary supporting plate.

Fig. 6- is a. sectional edge view showing a portion of the main head-plate and the au'iiliary supporting plate positioned'thereon relative to the main plate before being drawn up by the strain of the connecting bolts.

My present invention relates more particularly to the construction of a beam, reel, spool or other similar article of manufacture by folding, swaging or otherwise forming bendable or ductile sheet metal.

In carrying out this invention I provide two heads 10 which are connected by a tubular body portion 11. The heads are constructed of sheet metal and each head comprises a main plate 12 cut from sheet stock in disk form and its outer edge or periphery is bent outwardly as at 13 to form an annnlar, outwardly extending, stiffening flange. This plate 16, as illustrated in Figs. 1 and 2, is pressed outwardly at intervals as at 11-, providing a plurality of radially-disposed, stiffening ribs.

Specification of Letters Patent.

Serial No. 322,699.

It is found in practice that a beam-head constructed of a sheet metal plate, even provided with ribs, is not sutlidiently stiff to the surface line of the body portion, I have constructed an auxiliary plate or disk 15 whose outer edge 16 is turned inwardly from the plane of the plate so that this edge will engage the outer surface of the main head-plate adjacent the periphery of the latter or on a line intermediate the periphcry of the surface line of the body portion; and I have offset the edge of this auxiliary plate at the points 17 where it meets the ribs 15 so that this edge will rest upon the surface of the main plate between the ribs.

I have also provided recessed portions 18 at intervals about the center of this plate or inside the circle of the outer surface 'of the body portion for the purpose of receiving the heads 19 and nuts 22 of the tie bolts 20, but the inner surfaces 21 of these recessed portions 18 when originally formed and p0 sitioned stand slightly apart from the outer surface of the main head-plate, see Fig. 6, so that when the setting-up strain on these binding bolts 20 is exerted upon this plate the outer edge 16 thereof is forced with a supporting strain against the main plate, the

outer plate springing inwardly until the inner surface 21 of these recesses bring up against the adjacent surface of the main plate whereby this surface 21 serves as a stlop to limit the inward spring of the outer ate. p In Figs-1 and 2. I have shown a centralizing disk 23 located at either end within the body portion 11, and I have also shown a central hub'member 24 which is reduced slightly at its opposite ends and passed through all three of these plates viz: the centralizing disk; the main head-plate 12 and the outer auxiliary plate 15 and the ends 25 of this hub are riveted over to bind and secure all three of these plates together at either end of the beam.

In Figs. 3 and 4-, I have shown a modified form of reel in which the centralizing disks are omitted, the bolts 29 being employed to solely centralize the body 30 and instead of the central hub 24, shown .in Fig. 2, hub members 26 are riveted through both the auxiliary head-plate 27 and the main headplate 28.

The foregoing description is directed toward the construction illustrated, but desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims. I

I claim:

1. In a reel or beam, a body portion having a head at either end, each of saidheads comprising a main plate and an auxiliary supporting plate, said auxiliary plate .having a stiffening inturned edge or flange enaging and supporting said main plate ad- ]acent its periphery, and bolts passing through both of said plates to exert a pressure on said auxiliaryplate about its outer ridge and also binding saidheads to said ody.

2. In a device of the character described, a body portion having a head at either end, each head comprising a main plate and an auxiliary supporting plate, said auxiliary plate having an inturned stiffening edge or flange-engaging said main plate intermediate its periphery and the circumferential line of said body portion, binding bolts pass"- ing through both said main and auxiliary lates at points between the circumferential ine of said body and the inturned edge of said auxiliary plate, to bind said heads to said body, said supporting plate being primarily spaced from said main plate about said binding bolts whereby the setting up of said bolts causes the maximum strain to be exerted about the outer edge of said auxiliary plate.

3. In a reel or beam a body portion hav: ing a head at either end thereof, each of said heads comprising a main plate and an auxiliary supporting plate said auxiliary late having an inturned stiil'ening edge'or ange engaging and supporting said main plate on a circle within its periphery, said auxiliary plate being provided wlth bolt-head receiving depressions and tie bolts exerting a tension through said auxiliary plates to bind the heads to the ends of the body, the bottom wall of said depressions serving to form a stop to limit the inward s ring of said plate by the tension on said b0 ts.

4. In a reel or beam, a body portion having ahead at either end, each of said heads comprising a main plate and an auxiliary supporting plate, said auxiliary plate having an inturned stifi'ening edge or flange engaging and supporting said main plate adjacent its periphery, and bolts passing through both of said plates to exert a pressure on said auxiliary plates about their outer edges and also binding said heads to said body, and means for centrally locating and supporting the body on the heads.

In testimony whereof I aflix my signature.

FRANK MOSS'BERG.
